אָמַר רַבִּי חִיָּיא: הָרוֹצֶה לִרְאוֹת בְּאֵרָהּ שֶׁל מִרְיָם יַעֲלֶה לְרֹאשׁ הַכַּרְמֶל וְיִצְפֶּה וְיִרְאֶה כְּמִין כְּבָרָה בַּיָּם — וְזוֹ הִיא בְּאֵרָהּ שֶׁל מִרְיָם. אָמַר רַב: מַעְיָן הַמִּיטַּלְטֵל טָהוֹר — וְזֶהוּ בְּאֵרָהּ שֶׁל מִרְיָם.
Because of its similarity to Rabbi Ḥanina’s statement, the Gemara cites that which Rabbi Ḥiyya said: One who wants to see Miriam’s well, which accompanied the Jewish people throughout their sojourn in the desert, should do the following: He should climb to the top of Mount Carmel and look out, and he will see a rock that looks like a sieve in the sea, and that is Miriam’s well. Rav said: A spring that is portable, i.e., that moves from place to place, is ritually pure and is regarded as an actual spring and not as drawn water…
מיתיבי ר' יוסי בר' יהודה אומר שלשה פרנסים טובים עמדו לישראל אלו הן משה ואהרן ומרים וג' מתנות טובות ניתנו על ידם ואלו הן באר וענן ומן באר בזכות מרים עמוד ענן בזכות אהרן מן בזכות משה מתה מרים נסתלק הבאר שנאמר (במדבר כ, א) ותמת שם מרים וכתיב בתריה ולא היה מים לעדה וחזרה בזכות שניהן
The Gemara raises an objection from a baraita: Rabbi Yosei, son of Rabbi Yehuda, says: Three good sustainers rose up for the Jewish people during the exodus from Egypt, and they are: Moses, Aaron and Miriam. And three good gifts were given from Heaven through their agency, and these are they: The well of water, the pillar of cloud, and the manna. He elaborates: The well was given to the Jewish people in the merit of Miriam; the pillar of cloud was in the merit of Aaron; and the manna in the merit of Moses. When Miriam died the well disappeared, as it is stated: “And Miriam died there” (Numbers 20:1), and it says thereafter in the next verse: “And there was no water for the congregation” (Numbers 20:2). But the well returned in the merit of both Moses and Aaron.
